#include "lldb/lldb-python.h"
Committing type format code for Enrico Granata. This commit adds a new top level command named "type". Currently this command implements three commands: type format add <format> <typename1> [<typename2> ...] type format delete <typename1> [<typename2> ...] type format list [<typename1> [<typename2>] ...] This allows you to specify the default format that will be used to display types when you use "frame variable" or "expression", or the SBValue classes. Examples: // Format uint*_t as hex type format add x uint16_t uint32_t uint64_t // Format intptr_t as a pointer type format add p intptr_t The format characters are the same as "printf" for the most part with many additions. These format character specifiers are also used in many other commands ("frame variable" for one). The current list of format characters include: a - char buffer b - binary B - boolean c - char C - printable char d - signed decimal e - float f - float g - float i - signed decimal I - complex integer o - octal O - OSType p - pointer s - c-string u - unsigned decimal x - hex X - complex float y - bytes Y - bytes with ASCII llvm-svn: 133728

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

Added the infrastructure necessary for plug-ins to be able to add their own settings instead of having settings added to existing ones. In particular "target.disable-kext-loading" was added to "target" where it should actually be specific to the the dynamic loader plugin. Now the plug-in manager has the ability to create settings at the root level starting with "plugin". Each plug-in type can add new sub dictionaries, and then each plug-in can register a setting dictionary under its own short name. For example the DynamicLoaderDarwinKernel plug-in now registers a setting dictionary at: plugin dynamic-loader macosx-kernel (bool) disable-kext-loading To settings can be set using: (lldb) settings set plugin.dynamic-loader.macosx-kernel.disable-kext-loading true I currently only hooked up the DynamicLoader plug-ins, but the code is very easy to duplicate when and if we need settings for other plug-ins. llvm-svn: 166294

#include "lldb/Core/PluginManager.h"
While implementing unwind information using UnwindAssemblyInstEmulation I ran into some cleanup I have been wanting to do when reading/writing registers. Previously all RegisterContext subclasses would need to implement: virtual bool ReadRegisterBytes (uint32_t reg, DataExtractor &data); virtual bool WriteRegisterBytes (uint32_t reg, DataExtractor &data, uint32_t data_offset = 0); There is now a new class specifically designed to hold register values: lldb_private::RegisterValue The new register context calls that subclasses must implement are: virtual bool ReadRegister (const RegisterInfo *reg_info, RegisterValue &reg_value) = 0; virtual bool WriteRegister (const RegisterInfo *reg_info, const RegisterValue &reg_value) = 0; The RegisterValue class must be big enough to handle any register value. The class contains an enumeration for the value type, and then a union for the data value. Any integer/float values are stored directly in an appropriate host integer/float. Anything bigger is stored in a byte buffer that has a length and byte order. The RegisterValue class also knows how to copy register value bytes into in a buffer with a specified byte order which can be used to write the register value down into memory, and this does the right thing when not all bytes from the register values are needed (getting a uint8 from a uint32 register value..). All RegiterContext and other sources have been switched over to using the new regiter value class. llvm-svn: 131096

Merging the iohandler branch back into main. The many many benefits include: 1 - Input/Output/Error streams are now handled as real streams not a push style input 2 - auto completion in python embedded interpreter 3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use 4 - it is now possible to use curses to drive LLDB (please try the "gui" command) We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases. llvm-svn: 200263

#include "lldb/Core/StreamFile.h"
Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

<rdar://problem/12978143> Data formatters now cache themselves. This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval. Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization. The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime. Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type. Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose. llvm-svn: 173728

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation: - no setting auto completion - very manual and error prone way of getting/setting variables - tons of code duplication - useless instance names for processes, threads Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing". llvm-svn: 162366

<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}".

#include "lldb/Target/RegisterContext.h"
Fixed internal code to not link against and code from "lldb/API/*". lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used. Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number. Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings. llvm-svn: 196141

Added the ability to run expressions in any command. Expressions can be inserted in commands by using backticks: (lldb) memory read `$rsp-16` `$rsp+16` (lldb) memory read -c `(int)strlen(argv[0])` `argv[0]` The result of the expression will be inserted into the command as a sort of preprocess stage where this gets done first. We might need to tweak where this preprocess stage goes, but it is very functional already. Added ansi color support to the Debugger::FormatPrompt() so you can use things like "${ansi.fg.blue}" and "${ansi.bold}" many more. This helps in adding colors to your prompts without needing to know the ANSI color code strings. llvm-svn: 141948

"{, name = '${thread.name}'}"\
"{, queue = '${thread.queue}'}"\
Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation: - no setting auto completion - very manual and error prone way of getting/setting variables - tons of code duplication - useless instance names for processes, threads Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing". llvm-svn: 162366

<rdar://problem/12022079> Added a new "interpreter" properties to encapsulate any properties for the command interpreter. Right now this contains only "expand-regex-aliases", so you can now enable (disabled by default) the echoing of the command that a regular expression alias expands to: (lldb) b main Breakpoint created: 1: name = 'main', locations = 1 Note that the expanded regular expression command wasn't shown by default. You can enable it if you want to: (lldb) settings set interpreter.expand-regex-aliases true (lldb) b main breakpoint set --name 'main' Breakpoint created: 1: name = 'main', locations = 1 Also enabled auto completion for enumeration option values (OptionValueEnumeration) and for boolean option values (OptionValueBoolean). Fixed auto completion for settings names when nothing has been type (it should show all settings). llvm-svn: 162418

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Added the infrastructure necessary for plug-ins to be able to add their own settings instead of having settings added to existing ones. In particular "target.disable-kext-loading" was added to "target" where it should actually be specific to the the dynamic loader plugin. Now the plug-in manager has the ability to create settings at the root level starting with "plugin". Each plug-in type can add new sub dictionaries, and then each plug-in can register a setting dictionary under its own short name. For example the DynamicLoaderDarwinKernel plug-in now registers a setting dictionary at: plugin dynamic-loader macosx-kernel (bool) disable-kext-loading To settings can be set using: (lldb) settings set plugin.dynamic-loader.macosx-kernel.disable-kext-loading true I currently only hooked up the DynamicLoader plug-ins, but the code is very easy to duplicate when and if we need settings for other plug-ins. llvm-svn: 166294

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable.

Fixed internal code to not link against and code from "lldb/API/*". lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used. Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number. Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings. llvm-svn: 196141

The only flag is currently for parsing escape sequences. Not the prompt string can have escape characters translate which will allow colors in the prompt. Added functions to Args that will parse the escape sequences in a string, and also re-encode the escape sequences for display.

Many GDB users always want to display disassembly when they stop by using something like "display/4i $pc" (or something like this). With LLDB we already were showing 3 lines of source before and 3 lines of source after the current source line when showing a stop context. We now improve this by allowing the user to control the number of lines with the new "stop-line-count-before" and "stop-line-count-after" settings. Also, there is a new setting for how many disassembly lines to show: "stop-disassembly-count". This will control how many source lines are shown when there is no source or when we have no source line info. settings set stop-line-count-before 3 settings set stop-line-count-after 3 settings set stop-disassembly-count 4 settings set stop-disassembly-display no-source The default values are set as shown above and allow 3 lines of source before and after (what we used to do) the current stop location, and will display 4 lines of disassembly if the source is not available or if we have no debug info. If both "stop-source-context-before" and "stop-source-context-after" are set to zero, this will disable showing any source when stopped. The "stop-disassembly-display" setting is an enumeration that allows you to control when to display disassembly. It has 3 possible values: "never" - never show disassembly no matter what "no-source" - only show disassembly when there is no source line info or the source files are missing "always" - always show disassembly. llvm-svn: 145050

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Debugger::SetPrompt(const char *p)
Many GDB users always want to display disassembly when they stop by using something like "display/4i $pc" (or something like this). With LLDB we already were showing 3 lines of source before and 3 lines of source after the current source line when showing a stop context. We now improve this by allowing the user to control the number of lines with the new "stop-line-count-before" and "stop-line-count-after" settings. Also, there is a new setting for how many disassembly lines to show: "stop-disassembly-count". This will control how many source lines are shown when there is no source or when we have no source line info. settings set stop-line-count-before 3 settings set stop-line-count-after 3 settings set stop-disassembly-count 4 settings set stop-disassembly-display no-source The default values are set as shown above and allow 3 lines of source before and after (what we used to do) the current stop location, and will display 4 lines of disassembly if the source is not available or if we have no debug info. If both "stop-source-context-before" and "stop-source-context-after" are set to zero, this will disable showing any source when stopped. The "stop-disassembly-display" setting is an enumeration that allows you to control when to display disassembly. It has 3 possible values: "never" - never show disassembly no matter what "no-source" - only show disassembly when there is no source line info or the source files are missing "always" - always show disassembly. llvm-svn: 145050

Merging the iohandler branch back into main. The many many benefits include: 1 - Input/Output/Error streams are now handled as real streams not a push style input 2 - auto completion in python embedded interpreter 3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use 4 - it is now possible to use curses to drive LLDB (please try the "gui" command) We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases. llvm-svn: 200263

Many GDB users always want to display disassembly when they stop by using something like "display/4i $pc" (or something like this). With LLDB we already were showing 3 lines of source before and 3 lines of source after the current source line when showing a stop context. We now improve this by allowing the user to control the number of lines with the new "stop-line-count-before" and "stop-line-count-after" settings. Also, there is a new setting for how many disassembly lines to show: "stop-disassembly-count".

If both "stop-source-context-before" and "stop-source-context-after" are set to zero, this will disable showing any source when stopped. The "stop-disassembly-display" setting is an enumeration that allows you to control when to display disassembly.

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation: - no setting auto completion - very manual and error prone way of getting/setting variables - tons of code duplication - useless instance names for processes, threads Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing". llvm-svn: 162366

Cleaned up code that wasn't using the Initialize and Terminate paradigm by changing it to use it. There was an extra parameter added to the static accessor global user settings controllers that wasn't needed. A bool was being used as a parameter to the accessor just so it could be used to clean up the global user settings controller which is now fixed by splitting up the initialization into the "static void Class::Initialize()", access into the "static UserSettingsControllerSP & Class::GetSettingsController()", and cleanup into "static void Class::Terminate()". Also added initialize and terminate calls to the logging code to avoid issues when LLDB is shutting down. There were cases after the logging was switched over to use shared pointers where we could crash if the global destructor chain was being run and it causes the log to be destroyed and any any logging occurred. llvm-svn: 119757

Split up the Python script interpreter code to allow multiple script interpreter objects to exist within the same process (one script interpreter object per debugger object). The python script interpreter objects are all using the same global Python script interpreter; they use separate dictionaries to keep their data separate, and mutex's to prevent any object attempting to use the global Python interpreter when another object is already using it. llvm-svn: 123415

Fixed internal code to not link against and code from "lldb/API/*". lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used. Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number. Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing.

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached.

Added the infrastructure necessary for plug-ins to be able to add their own settings instead of having settings added to existing ones. In particular "target.disable-kext-loading" was added to "target" where it should actually be specific to the the dynamic loader plugin. Now the plug-in manager has the ability to create settings at the root level starting with "plugin". Each plug-in type can add new sub dictionaries, and then each plug-in can register a setting dictionary under its own short name. For example the DynamicLoaderDarwinKernel plug-in now registers a setting dictionary at: plugin dynamic-loader macosx-kernel (bool) disable-kext-loading To settings can be set using: (lldb) settings set plugin.dynamic-loader.macosx-kernel.disable-kext-loading true I currently only hooked up the DynamicLoader plug-ins, but the code is very easy to duplicate when and if we need settings for other plug-ins. llvm-svn: 166294

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached.

This is a very large commit that completely re-does the way lldb handles user settable internal variables (the equivalent of set/show variables in gdb). In addition to the basic infrastructure (most of which is defined in UserSettingsController.{h,cpp}, there are examples of two classes that have been set up to contain user settable variables (the Debugger and Process classes). The 'settings' command has been modified to be a command-subcommand structure, and the 'set', 'show' and 'append' commands have been moved into this sub-commabnd structure. The old StateVariable class has been completely replaced by this, and the state variable dictionary has been removed from the Command Interpreter. Places that formerly accessed the state variable mechanism have been modified to access the variables in this new structure instead (checking the term-width; getting/checking the prompt; etc.) Variables are attached to classes; there are two basic "flavors" of variables that can be set: "global" variables (static/class-wide), and "instance" variables (one per instance of the class). The whole thing has been set up so that any global or instance variable can be set at any time (e.g. on start up, in your .lldbinit file), whether or not any instances actually exist (there's a whole pending and default values mechanism to help deal with that). llvm-svn: 113041

Made the darwin host layer properly reap any child processes that it spawns. After recent changes we weren't reaping child processes resulting in many zombie processes. This was fixed by adding more settings to the ProcessLaunchOptions class that allow clients to specify a callback function and baton to be notified when their process dies. If one is not supplied a default callback will be used that "does the right thing". Cleaned up a race condition in the ProcessGDBRemote class that would attempt to monitor when debugserver died. Added an extra boolean to the process monitor callbacks that indicate if a process exited or not. If your process exited with a zero exit status and no signal, both items could be zero.

Made the darwin host layer properly reap any child processes that it spawns. After recent changes we weren't reaping child processes resulting in many zombie processes. This was fixed by adding more settings to the ProcessLaunchOptions class that allow clients to specify a callback function and baton to be notified when their process dies. If one is not supplied a default callback will be used that "does the right thing". Cleaned up a race condition in the ProcessGDBRemote class that would attempt to monitor when debugserver died.

lldb can deadlock when launched with an non-existing executable: % lldb /bin/nonono (lldb) target create "/bin/nonono" error: unable to find executable for '/usr/bin/nonono' <deadlock> The problem was the initial commands 'target create "/bin/nonono"' were put into a pipe and the command interpreter was being run with: void CommandInterpreter::RunCommandInterpreter(bool auto_handle_events, bool spawn_thread, CommandInterpreterRunOptions &options) { // Always re-create the command intepreter when we run it in case // any file handles have changed. bool force_create = true; m_debugger.PushIOHandler(GetIOHandler(force_create, &options)); m_stopped_for_crash = false; if (auto_handle_events) m_debugger.StartEventHandlerThread(); if (spawn_thread) { m_debugger.StartIOHandlerThread(); } else { m_debugger.ExecuteIOHanders(); if (auto_handle_events) m_debugger.StopEventHandlerThread(); } } If "auto_handle_events" was set to true and "spawn_thread" was false, we would execute: m_debugger.StartEventHandlerThread(); m_debugger.ExecuteIOHanders(); m_debugger.StopEventHandlerThread(); The problem was there was no synchonization in Debugger::StartEventHandlerThread() to ensure the event handler was listening to events and the the call to "m_debugger.StopEventHandlerThread()" would do: void Debugger::StopEventHandlerThread() { if (m_event_handler_thread.IsJoinable()) { GetCommandInterpreter().BroadcastEvent(CommandInterpreter::eBroadcastBitQuitCommandReceived); m_event_handler_thread.Join(nullptr); } } The problem was that the event thread might not be listening for the CommandInterpreter::eBroadcastBitQuitCommandReceived event yet. The solution is to make sure the Debugger::DefaultEventHandler() is listening to events before we return from Debugger::StartEventHandlerThread(). Once we have this synchonization we remove the race condition. This fixes radar: <rdar://problem/19041192> llvm-svn: 223083

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

Added more platform support. There are now some new commands: platform status -- gets status information for the selected platform platform create <platform-name> -- creates a new instance of a remote platform platform list -- list all available platforms platform select -- select a platform instance as the current platform (not working yet) When using "platform create" it will create a remote platform and make it the selected platform. For instances for iPhone OS debugging on Mac OS X one can do: (lldb) platform create remote-ios --sdk-version=4.0 Remote platform: iOS platform SDK version: 4.0 SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0" Not connected to a remote device. (lldb) file ~/Documents/a.out Current executable set to '~/Documents/a.out' (armv6). (lldb) image list [ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out [ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld [ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib Note that this is all happening prior to running _or_ connecting to a remote platform. Once connected to a remote platform the OS version might change which means we will need to update our dependecies. Also once we run, we will need to match up the actualy binaries with the actualy UUID's to files in the SDK, or download and cache them locally. This is just the start of the remote platforms, but this modification is the first iteration in getting the platforms really doing something. llvm-svn: 127934

When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

This patch captures and serializes all output being written by the command line driver, including the lldb prompt being output by editline, the asynchronous process output & error messages, and asynchronous messages written by target stop-hooks. As part of this it introduces a new Stream class, StreamAsynchronousIO. A StreamAsynchronousIO object is created with a broadcaster, who will eventually broadcast the stream's data for a listener to handle, and an event type indicating what type of event the broadcaster will broadcast. When the Write method is called on a StreamAsynchronousIO object, the data is appended to an internal string. When the Flush method is called on a StreamAsynchronousIO object, it broadcasts it's data string and clears the string. Anything in lldb-core that needs to generate asynchronous output for the end-user should use the StreamAsynchronousIO objects. I have also added a new notification type for InputReaders, to let them know that a asynchronous output has been written. This is to allow the input readers to, for example, refresh their prompts and lines, if desired. I added the case statements to all the input readers to catch this notification, but I haven't added any code for handling them yet (except to the IOChannel input reader). llvm-svn: 130721

This patch captures and serializes all output being written by the command line driver, including the lldb prompt being output by editline, the asynchronous process output & error messages, and asynchronous messages written by target stop-hooks. As part of this it introduces a new Stream class, StreamAsynchronousIO. A StreamAsynchronousIO object is created with a broadcaster, who will eventually broadcast the stream's data for a listener to handle, and an event type indicating what type of event the broadcaster will broadcast. When the Write method is called on a StreamAsynchronousIO object, the data is appended to an internal string. When the Flush method is called on a StreamAsynchronousIO object, it broadcasts it's data string and clears the string. Anything in lldb-core that needs to generate asynchronous output for the end-user should use the StreamAsynchronousIO objects. I have also added a new notification type for InputReaders, to let them know that a asynchronous output has been written. This is to allow the input readers to, for example, refresh their prompts and lines, if desired. I added the case statements to all the input readers to catch this notification, but I haven't added any code for handling them yet (except to the IOChannel input reader). llvm-svn: 130721

Command files that switch input handlers didn't work, now they do. The issue was when we called Debugger::RunIOHandler(), it would run the current IOHandler by activating it, and running it and then try to pop it and exit regardless of wether it was on top or not. The new code will push the IOHandler that was passed in, and run the IOHandlers until the one passed in is successfully popped. This allows files for the "command source" to switch input handlers: % cat /tmp/commands br s -S alignLeftEdges: br command add bt frame var po self DONE b s -n main br command add bt frame var DONE Note above we set a breakpoint, then add commands do it. The "br command add" will push the breakpoint comment gatherer until it sees "DONE" and then pop itself off the stack. The a new breakpoint will be set and it does the same thing again. Now this file can be sourced from the command line: % lldb -s /tmp/commands /path/to/a.out And your breakpoints will be correctly setup! <rdar://problem/17081650> llvm-svn: 211329

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

This is a very large commit that completely re-does the way lldb handles user settable internal variables (the equivalent of set/show variables in gdb). In addition to the basic infrastructure (most of which is defined in UserSettingsController.{h,cpp}, there are examples of two classes that have been set up to contain user settable variables (the Debugger and Process classes). The 'settings' command has been modified to be a command-subcommand structure, and the 'set', 'show' and 'append' commands have been moved into this sub-commabnd structure. The old StateVariable class has been completely replaced by this, and the state variable dictionary has been removed from the Command Interpreter. Places that formerly accessed the state variable mechanism have been modified to access the variables in this new structure instead (checking the term-width; getting/checking the prompt; etc.) Variables are attached to classes; there are two basic "flavors" of variables that can be set: "global" variables (static/class-wide), and "instance" variables (one per instance of the class). The whole thing has been set up so that any global or instance variable can be set at any time (e.g. on start up, in your .lldbinit file), whether or not any instances actually exist (there's a whole pending and default values mechanism to help deal with that). llvm-svn: 113041

Core: preprocess out TestPromptFormats TestPromptFormats appears as though it may be a useful unit test. Unfortunately, there is no invocation mechanism in place right now. It is unclear how to add a unit test for this scenario to the existing tests. It would be ideal to remove this entirely, but I am hopeful that this can/will be pulled out into a test still since it uses a user accessible interface. llvm-svn: 204309

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

Roll back the changes I made in r193907 which created a new Frame pure virtual base class and made StackFrame a subclass of that. As I started to build on top of that arrangement today, I found that it wasn't working out like I intended. Instead I'll try sticking with the single StackFrame class -- there's too much code duplication to make a more complicated class hierarchy sensible I think. llvm-svn: 193983

There are now to new "settings set" variables that live in each debugger instance: settings set frame-format <string> settings set thread-format <string> This allows users to control the information that is seen when dumping threads and frames. The default values are set such that they do what they used to do prior to changing over the the user defined formats. This allows users with terminals that can display color to make different items different colors using the escape control codes. A few alias examples that will colorize your thread and frame prompts are: settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n' settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n' A quick web search for "colorize terminal output" should allow you to see what you can do to make your output look like you want it. The "settings set" commands above can of course be added to your ~/.lldbinit file for permanent use. Changed the pure virtual void ExecutionContextScope::Calculate (ExecutionContext&); To: void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&); I did this because this is a class that anything in the execution context heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell you what it was really trying to do unless you look at the parameter. llvm-svn: 115485

Core: preprocess out TestPromptFormats TestPromptFormats appears as though it may be a useful unit test. Unfortunately, there is no invocation mechanism in place right now. It is unclear how to add a unit test for this scenario to the existing tests. It would be ideal to remove this entirely, but I am hopeful that this can/will be pulled out into a test still since it uses a user accessible interface. llvm-svn: 204309

This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

Fixed some issues with ARM backtraces by not processing any push/pop instructions if they are conditional. Also fixed issues where the PC wasn't getting bit zero stripped for ARM targets when a stack frame was thumb. We now properly call through the GetOpcodeLoadAddress() functions to make sure the addresses are properly stripped for any targets that may decorate up their addresses. We now don't pass the SIGSTOP signals along. We can revisit this soon, but currently this was interfering with debugging some older ARM targets that don't have vCont support in the GDB server. llvm-svn: 134461

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

FormatPromptRecurse
Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

This commit adds a new top subcommand "summary" to command type named "type". Currently this command implements three commands: type summary add <format> <typename1> [<typename2> ...] type summary delete <typename1> [<typename2> ...] type summary list [<typename1> [<typename2>] ...] type summary clear This allows you to specify the default format that will be used to display summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes.

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

Massive enumeration name changes: a number of enums in ValueObject were not following the naming pattern Changes to synthetic children: - the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed - making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly) claim to itself be synthetic - cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible - major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself - removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place) Some clean ups to the summary generation code Centralized the code that clears out user-visible strings and data in ValueObject More efficient summaries for libc++ containers llvm-svn: 153061

Fixed an issue where a pointer's address was being logged instead of its value Access to synthetic children by name: if your object has a synthetic child named foo you can now type frame variable object.foo (or ->foo if you have a pointer) and that will print the value of the synthetic child (if your object has an actual child named foo, the actual child prevails!) this behavior should also work in summaries, and you should be able to use ${var.foo} and ${svar.foo} interchangeably (but using svar.foo will mask an actual child named foo) llvm-svn: 137314

Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. llvm-svn: 186130

Massive enumeration name changes: a number of enums in ValueObject were not following the naming pattern Changes to synthetic children: - the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed - making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly) claim to itself be synthetic - cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible - major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself - removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place) Some clean ups to the summary generation code Centralized the code that clears out user-visible strings and data in ValueObject More efficient summaries for libc++ containers llvm-svn: 153061

This checking is part one of trying to add some threading safety to our internals. The first part of this is to use a new class: lldb_private::ExecutionContextRef This class holds onto weak pointers to the target, process, thread and frame and it also contains the thread ID and frame Stack ID in case the thread and frame objects go away and come back as new objects that represent the same logical thread/frame. ExecutionContextRef objcets have accessors to access shared pointers for the target, process, thread and frame which might return NULL if the backing object is no longer available. This allows for references to persistent program state without needing to hold a shared pointer to each object and potentially keeping that object around for longer than it needs to be. You can also "Lock" and ExecutionContextRef (which contains weak pointers) object into an ExecutionContext (which contains strong, or shared pointers) with code like ExecutionContext exe_ctx (my_obj->GetExectionContextRef().Lock()); llvm-svn: 150801

Converted the lldb_private::Process over to use the intrusive shared pointers. Changed the ExecutionContext over to use shared pointers for the target, process, thread and frame since these objects can easily go away at any time and any object that was holding onto an ExecutionContext was running the risk of using a bad object. Now that the shared pointers for target, process, thread and frame are just a single pointer (they all use the instrusive shared pointers) the execution context is much safer and still the same size. Made the shared pointers in the the ExecutionContext class protected and made accessors for all of the various ways to get at the pointers, references, and shared pointers. llvm-svn: 140298

Currently this command implements three commands: type summary add <format> <typename1> [<typename2> ...] type summary delete <typename1> [<typename2> ...] type summary list [<typename1> [<typename2>] ...] type summary clear This allows you to specify the default format that will be used to display summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes.

new syntax for summary strings: - ${*expr} now simply means to dereference expr before actually using it - bitfields, array ranges and pointer ranges now work in a (hopefully) more natural and language-compliant way a new class TypeHierarchyNavigator replicates the behavior of the FormatManager in going through type hierarchies when one-lining summary strings, children's summaries can be used as well as values llvm-svn: 134458

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

Operating system plug-ins can now return have a "core" key/value pair in each thread dictionary for the OperatingSystemPython plug-ins which allows the core threads to be contained with memory threads. It also allows these memory threads to be stepped, resumed, and controlled just as if they were the actual backing threads themselves. A few things are introduced: - lldb_private::Thread now has a GetProtocolID() method which returns the thread protocol ID for a given thread. The protocol ID (Thread::GetProtocolID()) is usually the same as the thread id (Thread::GetID()), but it can differ when a memory thread has its own id, but is backed by an actual API thread. - Cleaned up the Thread::WillResume() code to do the mandatory parts in Thread::ShouldResume(), and let the thread subclasses override the Thread::WillResume() which is now just a notification. - Cleaned up ClearStackFrames() implementations so that fewer thread subclasses needed to override them - Changed the POSIXThread class a bit since it overrode Thread::WillResume(). It is doing the wrong thing by calling "Thread::SetResumeState()" on its own, this shouldn't be done by thread subclasses, but the current code might rely on it so I left it in with a TODO comment with an explanation. llvm-svn: 180886

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

There were many issues with the previous implementation: - no setting auto completion - very manual and error prone way of getting/setting variables - tons of code duplication - useless instance names for processes, threads Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing". llvm-svn: 162366

There are now to new "settings set" variables that live in each debugger instance: settings set frame-format <string> settings set thread-format <string> This allows users to control the information that is seen when dumping threads and frames. The default values are set such that they do what they used to do prior to changing over the the user defined formats. This allows users with terminals that can display color to make different items different colors using the escape control codes. A few alias examples that will colorize your thread and frame prompts are: settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n' settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n' A quick web search for "colorize terminal output" should allow you to see what you can do to make your output look like you want it. The "settings set" commands above can of course be added to your ~/.lldbinit file for permanent use. Changed the pure virtual void ExecutionContextScope::Calculate (ExecutionContext&); To: void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&); I did this because this is a class that anything in the execution context heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell you what it was really trying to do unless you look at the parameter. llvm-svn: 115485

Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up doing was: - Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple to give us the machine type from llvm::Triple::ArchType. - There is a new ArchSpec::Core definition which further qualifies the CPU core we are dealing with into a single enumeration. If you need support for a new Core and want to debug it in LLDB, it must be added to this list. In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. llvm-svn: 126278

The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing". llvm-svn: 162366

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable.

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable.

The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

<rdar://problem/13621080> This commit changes the ${function.name-with-args} prompt keyword to also tackle structs Previously, since aggregates have no values, this would show up as foo=(null) This checkin changes that to instead print foo=(Foo at 0x123) (i.e. typename at address) There are other potential choices here (summary, one-liner printout of all members, ...) and I would love to hear feedback about better options, if any llvm-svn: 181462

When attempting to print function names with arguments in frame formatting, attempt to detect templated functions, and replace the argument list with values outside the template marking. Turns C::f<(this=0x00007fff5fbffb70, x=2, y=1)0>(int, int) into C::f<(C::V)0>(this=0x00007fff5fbffb70, x=2, y=1), which definitely looks more like the real thing.

Fixed an issue in the debugger format strings that include "${function.name-with-args}" where we grabbed the variable list size from the wrong list (we needed it from "args" and we were getting it from "variable_list_sp"). llvm-svn: 148425

Added a new thread and frame format that can be used to display a function name + arguments when the data is available. It seems to work really well, but some more testing is needed before we make this on by default. The new function format name is: ${function.name-with-args} To see how to use these formats see the website: http://lldb.llvm.org/formats.html Here is a sample backtrace of debugging LLDB with LLDB

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....".

So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

Add a new disassembly-format specification so that the disassembler output style can be customized. Change the built-in default to be more similar to gdb's disassembly formatting. The disassembly-format for a gdb-like output is ${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: The disassembly-format for the lldb style output is {${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: The two backticks in the lldb style formatter triggers the sub-expression evaluation in CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to use ' characters instead of ` would work around that. <rdar://problem/9885398> llvm-svn: 219544

Roll back the changes I made in r193907 which created a new Frame pure virtual base class and made StackFrame a subclass of that. As I started to build on top of that arrangement today, I found that it wasn't working out like I intended. Instead I'll try sticking with the single StackFrame class -- there's too much code duplication to make a more complicated class hierarchy sensible I think. llvm-svn: 193983

Converted the lldb_private::Process over to use the intrusive shared pointers. Changed the ExecutionContext over to use shared pointers for the target, process, thread and frame since these objects can easily go away at any time and any object that was holding onto an ExecutionContext was running the risk of using a bad object. Now that the shared pointers for target, process, thread and frame are just a single pointer (they all use the instrusive shared pointers) the execution context is much safer and still the same size. Made the shared pointers in the the ExecutionContext class protected and made accessors for all of the various ways to get at the pointers, references, and shared pointers. llvm-svn: 140298

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

Roll back the changes I made in r193907 which created a new Frame pure virtual base class and made StackFrame a subclass of that. As I started to build on top of that arrangement today, I found that it wasn't working out like I intended. Instead I'll try sticking with the single StackFrame class -- there's too much code duplication to make a more complicated class hierarchy sensible I think. llvm-svn: 193983

While implementing unwind information using UnwindAssemblyInstEmulation I ran into some cleanup I have been wanting to do when reading/writing registers. Previously all RegisterContext subclasses would need to implement: virtual bool ReadRegisterBytes (uint32_t reg, DataExtractor &data); virtual bool WriteRegisterBytes (uint32_t reg, DataExtractor &data, uint32_t data_offset = 0); There is now a new class specifically designed to hold register values: lldb_private::RegisterValue The new register context calls that subclasses must implement are: virtual bool ReadRegister (const RegisterInfo *reg_info, RegisterValue &reg_value) = 0; virtual bool WriteRegister (const RegisterInfo *reg_info, const RegisterValue &reg_value) = 0; The RegisterValue class must be big enough to handle any register value. The class contains an enumeration for the value type, and then a union for the data value. Any integer/float values are stored directly in an appropriate host integer/float. Anything bigger is stored in a byte buffer that has a length and byte order. The RegisterValue class also knows how to copy register value bytes into in a buffer with a specified byte order which can be used to write the register value down into memory, and this does the right thing when not all bytes from the register values are needed (getting a uint8 from a uint32 register value..). All RegiterContext and other sources have been switched over to using the new regiter value class. llvm-svn: 131096

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable.

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

Added code that will allow completely customizable prompts for use in replacing the "(lldb)" prompt, the "frame #1..." displays when doing stack backtracing and the "thread #1....". This will allow you to see exactly the information that you want to see where you want to see it. This currently isn't hookup up to the prompts yet, but it will be soon. So what is the format of the prompts? Prompts can contain variables that have access to the current program state. Variables are text that appears in between a prefix of "${" and ends with a "}". Some of the interesting variables include: // The frame index (0, 1, 2, 3...) ${frame.index} // common frame registers with generic names ${frame.pc} ${frame.sp} ${frame.fp} ${frame.ra} ${frame.flags} // Access to any frame registers by name where REGNAME is any register name: ${frame.reg.REGNAME} // The current compile unit file where the frame is located ${file.basename} ${file.fullpath} // Function information ${function.name} ${function.pc-offset} // Process info ${process.file.basename} ${process.file.fullpath} ${process.id} ${process.name} // Thread info ${thread.id} ${thread.index} ${thread.name} ${thread.queue} ${thread.stop-reason} // Target information ${target.arch} // The current module for the current frame (the shared library or executable // that contains the current frame PC value): ${module.file.basename} ${module.file.fullpath} // Access to the line entry for where the current frame is when your thread // is stopped: ${line.file.basename} ${line.file.fullpath} ${line.number} ${line.start-addr} ${line.end-addr} Many times the information that you might have in your prompt might not be available and you won't want it to print out if it isn't valid. To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character.

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

To take care of this you can enclose everything that must resolve into a scope. A scope is starts with '{' and ends with '}'. For example in order to only display the current file and line number when the information is available the format would be: "{ at {$line.file.basename}:${line.number}}" Broken down this is: start the scope: "{" format whose content will only be displayed if all information is available: "at {$line.file.basename}:${line.number}" end the scope: "}" We currently can represent the infomration we see when stopped at a frame: frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19 with the following format: "frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n" This breaks down to always print: "frame #${frame.index}: ${frame.pc} " only print the module followed by a tick if we have a valid module: "{${module.file.basename}`}" print the function name with optional offset: "{${function.name}{${function.pc-offset}}" print the line info if it is available: "{ at ${line.file.basename}:${line.number}}" then finish off with a newline: "\n" Notice you can also put newlines ("\n") and tabs and everything else you are used to putting in a format string when desensitized with the \ character. Cleaned up some of the user settings controller subclasses. All of them do not have any global settings variables and were all implementing stubs for the get/set global settings variable. Now there is a default version in UserSettingsController that will do nothing. llvm-svn: 114306

Make the "synchronous" mode actually work without race conditions. There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

This is the first step of making lldb able to create target-specific things (e.g. breakpoints, stop-hooks) before we have any targets - for instance in your ~/.lldbinit file. These will then get copied over to any new targets that get created. So far, you can only make stop-hooks. Breakpoints will have to learn to move themselves from target to target for us to get them from no-target to new-target. We should also make a command & SB API way to prime this ur-target. llvm-svn: 222600

Add the ability to set breakpoints with conditions, commands, etc, in the "dummy-target". The dummy target breakpoints prime all future targets. Breakpoints set before any target is created (e.g. breakpoints in ~/.lldbinit) automatically get set in the dummy target. You can also list, add & delete breakpoints from the dummy target using the "-D" flag, which is supported by most of the breakpoint commands. This removes a long-standing wart in lldb... <rdar://problem/10881487> llvm-svn: 223565

Breakpoints set before any target is created (e.g. breakpoints in ~/.lldbinit) automatically get set in the dummy target. You can also list, add & delete breakpoints from the dummy target using the "-D" flag, which is supported by most of the breakpoint commands. This removes a long-standing wart in lldb... <rdar://problem/10881487> llvm-svn: 223565

return target;
}
This is the first step of making lldb able to create target-specific things (e.g. breakpoints, stop-hooks) before we have any targets - for instance in your ~/.lldbinit file. These will then get copied over to any new targets that get created. So far, you can only make stop-hooks. Breakpoints will have to learn to move themselves from target to target for us to get them from no-target to new-target. We should also make a command & SB API way to prime this ur-target. llvm-svn: 222600

Merging the iohandler branch back into main. The many many benefits include: 1 - Input/Output/Error streams are now handled as real streams not a push style input 2 - auto completion in python embedded interpreter 3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use 4 - it is now possible to use curses to drive LLDB (please try the "gui" command) We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases. llvm-svn: 200263
